MELBOURNE, Australia — An Australian celebrity comedian has refused to apologize for gatecrashing a glamorous Melbourne wedding, leaving guests stunned by a series of “unfunny” stunts.

Wearing Groucho Marx masks and brandishing a rubber chicken and megaphone, Rod Quantock and 60 other uninvited guests interrupted a private function at a Melbourne restaurant, in Victoria, Saturday afternoon.

The reception takeover was part of Quantock’s award-winning roving show for the Melbourne International Comedy Festival (MICF), where he takes his audience on a tour of the city, hijacking shops, cafes and events with impromptu performances.

But guests say Quantock’s act was “uninvited, unwelcome, and very unfunny” and ruined what was otherwise a tasteful and painstakingly planned affair.

Wedding photographer Shannon McDonald said, “A lot of time and care went into planning this lovely couple’s wedding, and for Rod Quantock and his followers to disrupt it for their own amusement wasn’t funny or cool. It wasn’t his moment, it was theirs.”

Quantock, who won the MICF directors’ choice award for his act the same night as the wedding, was surprised he had offended the wedding party.

“I thought most people enjoyed it and those who didn’t — well, I couldn’t care less about them,” Quantock said.

“It was just a little bit of silliness that invaded their world for a few minutes.”
